7 Claims.

This invention relates to hair curlers and more particularly to those employing two clamping members and my object is to devise a simple curler of this character which is readily operated to effectively curl a lock of hair from one end to the other thereof and under even tension. Further objects I have in mind will hereinafter appear.

This invention is hereinafter fully described and illustrated by way of example, in the accompanying drawing in which Fig. 1 is a side elevation, on an enlarged scale of my curler;

Fig. 2 an end elevation of the parts shown in Fig. 1;

Fig. 3 a longitudinal section, on the same scale as Fig. 1;

Fig. 4 a perspective view, also enlarged, of the curler; and

Fig. 5 a cross section on the line 55 in Fig. 1.

In the drawing like numerals of reference indicate corresponding parts in the different figures.

I is a hollow mandrel which may be made of any suitable material such as plastic or thin metal and which may be perforated or slotted as indicated at 2. The mandrel may be slightly tapered longitudinally and is provided with a pair of transversely spaced apart lugs 3 having open bearings 4. formed in the mandrel between the lugs 3.

An inner clamping member 6 has an outward projection I carrying a pivot pin 8, the ends of which form trunnions which are journalled in the open bearings 4. also provided with an inward extension 9 which passes through the opening 5 for engagement by a spring III which tends to move the member into clamping engagement with the mandrel I. The outer end of the projection I is serrated for engagement by a finger of the operators hand to rock the clamping member on its pivot 8 to open said clamp. The member 6 may also be perforated or slotted as indicated at II.

A rectangular opening 5 is The clamping member is A knurled or serrated disc I2 is provided with a hub I3 received in one end of the mandrel I and secured thereto by means of a pin. I4. The pin is flush with the outside periphery of the mandrel on which a collar I5 is rotatably and axially mounted. On the collar is pivoted at I6 an outer clamping member I'I, which tapers in thickness towards the free end thereof.

The free end I8 of the outer clamping member I! has a ball and socket frictional engagement with a spindle I9 for releasably locking the outer clamp H in its operative position. The socket is formed by recessing the end I8 at 2|] to receive the semi-spherical ball 2| carried by or formed on the end of the spindle I9. Preferably the ball 2| is formed of resilient material suitably secured to a cup-shaped retainer 22 slidalbly mounted within the hollow mandrel I. The retainer 22 is carried by the spindle I9 which extendslongitudinally of the mandrel through a bore in the hub, I 3. The spindle is provided with an elongated slot 23 for the passage of the pin I4 and to permit a limited axial movement of the spindle relative to the pin I4.

The inward extension 9 on the inner clamping member 6 is provided with a hole or slot 24 through which the spindle I9 is passed to limit the outward movement of the trunnions 8 in the open bearings 4. The hole or slot 24 is of sufficient size to permit the member 6 to rock on its pivot 8 even should the pivot be shifted outwardly in its open bearings 4- which occurs when the ends of the lock of hair are clampedadjacent the trunnions 8.

On the spindle I9 is disposed the coil spring II) which tends to move the ball 2| to lock the outer clamping member H in its operative position and tends to rock the inner clamping member 6 to its operative position to clamp a lock of hair between it and the mandrel I. One end of the spring I0 engages the retainer 22 and the other end engages the extension 9 or a washer 26 interposed between the end of the spring and the extension so that the retainer, ball 2| and spindle I9 are moved in a direction opposite that imparted to the extension 9. Since the inner clamping member 6 is one arm. of a bell crank and the extension 9 the other arm thereof, the movement of the extension, by the spring I0, tends to urge the member 6 towards the mandrel When the outer clamp is swung to an inoperative position, the axial movement of the spindle I9- is limited by the engagement of the end of the slot 23 with the pin- I4 so that the inner clamping member 6 will still berocked, by the sp'ring I0, to its operative position.

With the possible exception of the ball 2| and spring I0 all the parts of the hair curler may'be made of plastic material. The end of the's'pin'dle holding the. clamp l1 and directly engaging the mandrel l and clamp 6 to turn them relative to the clamp 11. The collar (and thus the outer clamp I1) is then rotated on the mandrel l to enable the outer clamping member IT to be locked in its closed position to clamp the wound hair close to the scalp. Thus the lock of hair is fully curled, from one end to the other, under even tension throughout the length thereof.

It will be understood that various modifications may be readily made without departing from the spirit ofmy invention.

What I claim as my invention is:

1. A hair curler comprising a hollow mandrel; means for clamping the free ends of a group of hairs on said mandrel, the said means comprising a bell crank having a slidable pivotal connection with the mandrel, the bell crank having one arm co-operating therewith to form the clamp, the mandrel having an opening for the passage therethrough of the other arm of the bell crank; and a spring in the hollow mandrel for engaging the last mentioned arm to urge the first mentioned arm to its co-operative position with the mandrel, the sliding connection permitting the first mentioned arm to move in and out relative to the mandrel adjacent the pivotal connection.

clamp, the other arm of the bell crank extending through the opening; and a spring in the hollow mandrel for engaging the last mentioned arm to urge the first mentioned arm to its co-operative position relative to the mandrel, the open bearings permitting the first mentioned arm to move in and out relative to the mandrel adjacent the pivotal connection.

3. A hair curler comprising ahollow mandrel around which a group of hairs may be wound; a clamping member rotatably mounted on the mandrel and swingable relative thereto to clamp the group of hairs adjacent the scalp; means for frictionally retaining the clamping member in its operative position, the retaining means including a spindle axially movable in the hollow hairs on said mandrel, the said means p to clamping position.
